The awn role in yield formation and spring wheat grain quality

The research results of beardedness influence on yield formation and spring wheat grain quality on the basis of the developed analogues of the early ripe sort “Krasnoyarskaya” and mid-season sort “Vetluzhanka” are given in the article. It is shown that the feature contribution into formation of grain productivity and quality depends on the year conditions and sort genetic peculiarities. The reliable advantage on productivity of “Vetluzhanka” sort awned analogues in the moisture lack conditions in the ear formation period is noted. The existence of awns exerts positive influence on indices that characterize grain filling completeness (grain nature, the mass of 1000 grains, flour yield).
